Sounds quite coherent with all evidence we have seen so far- explaining
why he lifted off, didn't steer hardly at all, and maybe didn't
brace himself at all, making a bad accident much worse. I would like to
know more, if there are ANY details at all...

True, the classic heart attack (thrombosis, a coronary artery becoming clogged)
would be quite unusual in a person in his 30s in excellent condition. However,
heart failure due to a previously unknown congenital heart defect is not at all
unheard of among athletes. Apparently, being a athlete is a two-edged sword for
people like this: the fact that they are in exceptionally good condition makes
the heart stronger overall and may mask the defect. However, the extreme
physical stress they are often under during training and competition may make
them more susceptable to a catastrophic heart failure. (Just think of those
160+ pulse readings that we've seen from drivers wearing a heart monitor.)
Just to put some names to this: Bastekball player Pete Maravich died on the
court of heart failure--it was several years after he retired, but by all
accounts he was still in excellent condition. Boxer Evander Holyfield was
recently forced to retire because a heart problem was discovered after he
experienced chest pains during his most recent fight. I also seem to remember a
famous long-distance runner (Jim Fixx?) who died of a heart attack a few years
ago. There have been others, but you get the idea.
I'm not suggesting that's what happened to Senna: only the people who did the
autopsy could know that. Just don't rule it out solely because of his age &
conditioning.
Disclaimer: I'm not a doctor, nor do I play one on the net, but heart disease
runs in my family, and I'm in my 30s too, so I have a vested interest in the
topic.

Exactly! If Senna had had any chance of having a heart attack I
think that he wouldn't have been allowed to race. To my knowledge one
doesn't have a heart attack out of the blue. His doctor would know if he
was prone to this.
Yet more misinformation.

Yes, people in prime physical shape can suffer unexpected heart attacks.
Even athletes with no known pre-existing heart conditions.
> Yet more misinformation.
No more so than your statement that the suspension failed -- just another
possible cause for Senna's crash. It'd explain the lifting off and the
lack of any corrective action; we just don't have any solid evidence for
either this or the suspension breakage.

Sudden heart failure as would be experienced by an otherwise healthy
athlete is not the usual coronary episode that older people with
athersclerosis, ischemia or angina would suffer. Sudden heart failure as
would be experienced by a young athlete unexpectedly would most likely be
caused by one of two things: arrhythmia and a physical heart defect.
Arrhythmias are caused by defects in the electrical conduction nodes of
the heart's natural pacemakers. the Sino-atrial node (SA node), Atrio
Ventricular Node (AV), and the His-Perkunje bundle of fibers. Often these
heart arrhythmias are not discovered until it is too late because the
atheletes are considered otherwise healthy. There are usually warning
signs that lead to diagnosis like chest pain, dyspnea (shortness of
breath), etc. but often there are no warning signs. Reggie Lewis, a
Boston Celtic Basketball player died of a rare arrythmia defect. Often
the heart's natural pacemaker "short-circuits" and starts to race away out
of control, firing the muscles, but producing useless pumping activity,
and this is more likely to happen during high pulse rates -- exercise.
The other cause would be a physical heart defect. Most likely some
deformation of the heart valves. Most common are the aortic and mitral
valve defects, often caused through congenital transmission OR through
acquired disease in childhood (rheumatic fever, strep throat B)... This is
what I have, and how I got it. I can tell you, that in this case,
overexertion, much as would be experienced in race car driving Could,
remotely, trigger a massive heart failure. Usually, valve defect patients
experience what's known as congestive heart failure, which is a gradual
failure in the venous return of blood back to the heart. This is a
gradual process that would take minutes to hours. Howeve super exertion
could cause a massive myocardial infarction where the heart is suddenly
starved of oxygen and suffers "cardiac death" where the muscles start to
die. this is usually very sudden and without warning, and can happen in
susceptible individuals who have exceeded the exercise capacity of their
hearts. It is ironic that because of the heart defects, the hearts of
many patients are noticeably larger and stronger than the average person
to compensate for the valve defect, but at the same time, this puts the
heart in danger of being TOO big, and then it is in danger of passing the
critical point of elasticity during over-exertion. (this is what I have
to be careful about...) Signs? Wide peripheral blood pressure (150/50
is average for me), and a high resting pulse (80+), easily hitting 200
during hard exercise.
Did Senna die of this? I don't know. Did ESPN have the heart monitor on
him that race? Sometimes I remember seeing them sending that telemetry
and it was quite interesting...
Rest in peace, Aryton!

I remember a few (2 or 3) Dutch cyclists who died in the last 5-10 years due to
heart failure: One (or two) male[s] and one female.... Recently there seemed to
be another (Dutch) cyclist with heart problems ([un]regular heartbeat), but as
far as I know newer (research) results did not confirm this. All these persons
were/are athletes with very good medical staff around etc. etc.

News:
Guerrero's hot lap in the 92 Lola isn't surprising. It's the same car that
he set the official track record with in 1992.
Michael Greenfield was replaced by Johnny Parsons in the Greenfield
Industries 93 Lola-Greenfield. During practice, a gal in the stands
asked who had stalled the car on the track and when told it was Johnny
Parsons she inquired, "Is that Parsons JUNIOR?" :-)
So, was the Mercedes the first motor to detonate this month? No. That
honor goes to Michael A's Ford which blew up exiting turn 4 after posting
the fastest lap in his #8T. He was on the track about an hour later
in the #8.
Did anybody notice that Groff's Honda had a much deeper bass note than
Rahal's? My guess: different internals....
Why wasn't Stan Fox in his new Reynard? His team is waiting for his Ford
motor to arrive.
Speaking of Reynards, they have to do something about them front wings.
Either somebody broke them or didn't put them on right, they droop. :-)
Teams are ticked at USAC because of a rental charge of over $1000 dollars
for the new pop-off valves.
Stephan Gregoire's ride has dried up. Formula Project 500 withdrew the
entries.
Also withdrawn was the Tasman Motorsports Group car for Bryan Herta. It
looks fairly certain Herta will drive Foyt's #14. Announcement is
expected shortly.
The forty cars that practiced on the first day mark a new record for
opening day.
Rumors:
The reason that Paul Tracy ran in Little Al's #31? Little Al was at
Michigan running a simulated 500 mile race on the Mercedes in the #31T.
Penske will be rotating one driver to MIS to run the motor each day.
Forecast:
Weather looks good for tomorrow too. Remember your sunscreen.

Yes I did state that as if it were a fact. Chalk it up to my
increasing irritation with all the posters who are now seemingly convinced
that Senna made an error based upon a single piece of data. (Patrick
Head's claim that telemetry only showed Senna lifting) Whilst this is
likely true I wonder just what things telemetry can detect? Breaking
mechanical parts? I doubt it. At least we know it wasn't an engine blow up
that spewed oil on the tires. Also I'd guess that a broken half shaft is
also out since that may have affected the engine which was being
monitored.
What's more the fact that Senna lifted off the gas only once is
hard to reconcile with driver error. Wouldn't he have put the power back
on if he noticed he was losing grip? Also he had to have lifted at some
time... when he saw he was going to crash. Besides as someone else finally
pointed out the car wasn't anywhere near the limit of adhesion through
Tamburello. Lifting while going through Peralta would probably cause an
instant spin because there the car is probably right on the edge.
Murph
He hasn't practiced yet. As of 3PM on Monday he still hasn't been
on the track. Although, Smith, Ribbs, Gordon, Unser Jr, Herta,
and John Andretti have taken to the track earler today.
Top lap so far is Michael Andretti's 227.0 mph. Fittipladi has
"magically" found almost 10 mph of additional speed today....
(taken from the track updates on the radio - WIBC 1070AM to be exact)
One note I haven't seen yet in r.a.s.: the Chicago Tribune reported
this morning that on one of Brayton's laps Sunday, he had a trap speed
of over 243mph, which is apparently some sort of unofficial record.
Of course, they also said that some of the "experts" are predicting
a 260mph trap speed for the Penske "Mercedes" cars ... (250 I might
believe...)
I'd guess that the trap that caught Brayton at 243 was set up at the end
of the back straight - that's generally the fastest part of the track.
Fast trap speeds are not uncommon for the Buicks. Heck, way back in about
'86, Jim Crawford was seen at the end of a straight at 237mph. Unfortunately,
that was about a second or two before his huge shunt (he said his tach.
was malfunctioning, so he thought he was going a lot slower as he entered
the turn).
BTW, I thought that Brayton's car was listed as a '92 Lola. I thought
that was the last year that Lolas were built to house the Buick. Is '93
correct?

In the ~200mph environment, I don't think anything can be taken for granted.
Much like bullet ballistics, almost anything can happen. Who knows what
<a given driver> would actually do under those circumstances? Lift quick,
stomp hard, relax slowly?
Let's not forget that Evander Holyfield had to retire from boxing (not my "sport")
recently after going through a heavyweight bout in near-arrest because of
an undetected heart problem that was revealed only during the post-fight
examinations. His doctors were amazed that he lived through 12 rounds.
I'm not suprised that there is a skid mark. F1 tires often leave black marks,
even when cornering correctly, from their side-slipping. I do not recall
seeing these on any of the TV coverage I've seen. They do not necessarily
indicate braking.
I've never heard it called a *controlled* lift before. Where did this
come from ??
: that there were long black skid marks before the Tamborella which
From the replays I've seen, there was no evidence of wheel locking at all.
I could be wrong though.
: eminated from Senna's car .As I have not heard of these before I am
: wondering if it is just an inconsistancy .
: Any comments on the above would be appreciated.

The Penske speed is supposedly at the end of the front straight.

According to the charts I see it is. Then again, Menard did have a full
year to modify a car or 4.
According to Menard, Lola offered a Buick version the new Lola at twice
the price of the Ford or Ilmor version, about $800. Menard said
forget it and spent a lot of money updating their old cars. No idea
if those are '92 or '93 cars.

What I have on it isn't much. Basically a 209 cu-in V-8 built by Peter
Greenfield. I haven't seen much on it because of the hoopla over the
Mercedes. It is the same size as the Mercedes and competes in the same
engine class. It apparently gave good numbers on the dyno, but that doesn't
really mean much. I don't know if it uses any standard block though.
The Buick/Menard is a V-6 BTW.
No, it's a purpose built, pushrod, two valve like the Ilmor/M-B.

Yes, I agree that his doc would know. Senna submited to a physical and medical tests in March, 23, as he did each six mouths.

People,
While I state that I do not believe for a moment it was a heart attack,
don't kid yourself. Age, physical condition can make a difference, but
some of the best atheletres inthe world, in great shape, have suffered
heart attacks with NO prioe indication that it would happen. Doctors
have missed diagnoses before, even with all the modern tests and
technologoes. Even tho some doctors think they are Gods, they aren't.

True, certain people are *prone* too heart attack, but *anyone* can
have one. Witness the world-class marathon runner who died a while
back of a heart attack a few years back (whose name escapes me --
anyone remember his name?) I'm not saying Senna had a heart attack,
but a clean bill of health is *not* a guarantee against one.

i've been staying out of this discussion for several reasons, not the least
of which is that i don't think the evidence i've heard indicates that senna
had a heart attack. however, speaking as someone who's had three heart
attacks, i've decided to try to correct some of the mis-infomation i've
read on the net about heart attacks.
first, no medical exam can predict a heart attack. sure, the docs can tell
if you're in a group that is at high risk - but, for example, i had a complete
medical exam by a heart specialist; got a clean bill of health; and had a
heart attack three days later!
also, while some heart attacks produce heardly any disconfort, others produce
so much pain that it would be impossible to "allow time to safely pull off
the track".

At Waterford Hills track in Michigan at a club race, the first I ever
worked as a corner marshall, a FV driver had a heart attack, his Vee
flew off track on one side, crossed the infield backwards with the tires
spinning forwards until they gripped, then launched forwards back across
the infield to the track, crossed and ended up in some trees. Heart
attacks can be sudden and violent. The driver was given CPR and survived.
I'm not saying that A.S. had a CA, just that you don't always have time
to pull over and react.
